Double Reinforcement.

180 g/m² Nonwoven  Polyester  and 60 g/m² Fiberglass.


A high dimensional stability and impact resistant bituminous roll, torch applied, modified with atactic poly-propylene (APP). The membrane has excellent durability and flexibility at low temperatures, and ability to withstand high temperatures.

The non-woven fabric gives the superior mechanical resistance to stand fatigue and tear caused by different superficial movements of adjoining layers, while the inorganic reinforcement gives the membrane outstanding dimensional stability.

The upper face is covered with polyethylene film.

Field of Application:

  • To fix the sheet to the substrate, use a propane gas burner to melt off the polyethylene film and a thin layer of bitumen while unrolling and laying the membrane. Side laps 100 mm and end laps 150 mm.  Smoothen the overlaps with a hot round-tipped trowel.
  • Excessive heating may damage the reinforcement.
  • The membrane maybe loosely laid, partially or fully bonded, depending on the structure and the specifications.

Technical Specifications:
